To all who-mil? may concern:

Beit known that T, HENRY A. WISE WOQD, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and.

useful Web-Renewing Device, of which the following is a specification.

This invention relates to mechanism for providing a continuous supply ofweb for printing presses and other machines by connecting a fresh web tothe'end of an'expiring web.

The principal objects thereof are to pi*o vide an improved deviceforthis purpose which will operate eifectively without stopping thepress or slackening the speed, and at the same time to obviate thenecessity of moving the fresh web roll bodily after it is put inposition on the press and the necessity for threading the fresh web intoplace by hand; to provide means whereby a direct action between theexpiring and fresh rolls is secured for pressing one against the otherso as to unite the two webs under some degree of pressure; and to avoidcomplicated and troublesome constructions for the purpose of making thenew web adhere to the old one. 1

The webs are united, according to the present invention, by placingpaste on the end of the new web, revolving the new web roll at surfacespeed, and moving the expiring web and preferably its roll bodily intocontact with 1t. A perfect splice is made between them and by throwing aknife against the exhausted stub the expired web is severed and the stubstopped. It can then be taken out, its bearings moved back, and

a new web roll shaft set intothem before the other web is exhausted, andthen the operation can be repeated or, more properly speaking, reversed.

The invention also. involves improvements in details of construction andcombinations ofparts as will appear.

Reference is to be had to the accompanying drawings, in which- Fig. 1 isan end elevation of the paper roll end of a web press showing apreferred embodiment of this invention;

Fig. '2 is ahorizontal sectional view on the line 2--2 in Fig. 1;

Flg. 3 1s a diagrammatic view showing the positionof the parts as thefree end of diversion of the running web out of its path so as topaste'it to the new roll by pressing a roller against it at a pointbetween the old stub and the first guide roller. The latter arrangementinvolves some 'difliculties because the roll which is pressed againstthe web has to be started into operation by contact with the web runningat full speed and by its motion against the web it has to len then thecourse of the web.

his invention, as has been stated, does not involve either of themotions just above mentioned, but in their place the old web roll stubitself is moved, thus not making any new angle in the running course ofthe web or increasing in any way the difiiculty of its operation.

Referring particularly to Figs. 1 and 2, it will be seen that I haveillustrated the end of the frame 10 of a web press, the two side framesconstituting the support for the whole mechanism shown. On these framesare mounted bearing brackets 11,

one pair for each web roll A or B. Each of 5 have brake pulleys M. Thebrakes are supported on studs 15 mounted on stationary projections fromthe side frames 10. These brakes can be released entirely as the paperrolls become nearly exhausted so as not to interfere with the movementsof the paper roll stub up and down the frame. Details of the brakemechanism are not described herein as they do not constitute a part ofthis invention, and any desired type can be em loyed. v Q

he brackets '11 are mounted to slide up and down on the vertical edgesof the side frames 10, and they are provided with threaded projections.16 for receiving screws 17 and 18 arranged in'pairs on each side of thepress, one for each of the brackets. The screws 17 and 18 onthe sameside.

V which it is designed to be operated. The

worm wheels 23 are provided with clutch ends 29 on opposite sides whichare adapted to be engaged by clutch collars 30 on the adja'cent ends ofthe screws 17 orv 18 so as to permit transmission of rotation from thehand wheel to a shaft .above it or below it, as may be desired, theseclutch collars 30 of course being movable the distance required for thisoperation. By rotating the hand wheel. the two shafts 17 or 18, as thecase may be, on the two sides of the pressare turned and the brackets 11carried thereby can be raised or lowered.

Mounted between the twoshafts 17 and 18, and preferably extending fromthe bracket 19 which supports their adjacent ends, is an arm 31 on eachside. These carry a transverse shaft 32 at their end which is providedwith a saw-toothed knife 33. On the operating end of this shaft 32 is anarm 34 secured to it and adapted to be held normally in horizontalposition by a spring pin handle 35. A slight outward pull on this handlereleases it and allows the operator to swing the arm 34 so as tooscillate the knife blade 33 either up or down, as for example intoeither one of the positions indicated in Figs.

' 3 and 4. This cuts off the expiring web and stops its stub fromrevolving.

As has been the case in some of my devices heretofore designed for thisgeneral purpose, the press mechanism is designed to operate a verticalshaft 41 on one of the side frames, brackets 42 beingprovidedfor'supporting it and furnishing its bearings. This suppliespower through bevel gears 43- and friction wheels 44 and 45 to operate ashaft 46 having a friction bearing 47 designed to be controlled by ahandle 48 fixed to the shaft. This handle is normally held by 'a catch49 engaging a pin 50 and mounted on the side frame. When this catch isreleasedthe handle is swung over by a spring 51 which turns the shaft onits own center. Fixed on this shaft also is a frame comprising two arms52 supporting a shaft 53 extending across the machine which carriesfriction rolls 54 for rotating the fresh web roll as is well understoodin this art. The shaft 46 is connected with the shaft 53 by two gears55,

in the case shown above the driven gears 43,

and by three gears in the case shown below, so as to transmit therotation to the web roll in the right direction.

The operation of the device will be clearer from an inspection of Fig.3. As is usual, the idle reserve roll 13 has been pasted at its end. Asthe upper web roll A was about to become exhausted. the next to thelowest handle 48, shown in Fig. 1, was released and brought u so as tobring'the roll B up to web spee Then the brake operating on the spindleof roll A was released manually and the clutch sections connecting theworm. wheel 23, shown at the top of Fig.1, with the screw 18 below itwere brought together. Now the operator, leaving things in thatcondition, turns the hand wheel 27, at the to "of Fig. 1, and bringsdown the web rol A from the dotted line preferably all the way to thefull line position in Fig. 3, in which it contacts with the new web rollB. If it is not moved'into contact bodily the two webswill have to be.brought together, and I prefer to press them together etween theirrespectiverolls. It will be seen that this operation does no'tbring anyadditional angle into the line of motion of the web andthus introducesno complications. it .simply swings this part of the web as a wholeabout the guide roll 60 to which it passes, leaving the course of theweb straight between the web roll A and this guide roll.

Now'the spring pin handle 35 is drawn out and the arm 34 turned so as tobring the blade 33 uparound to the right into the position shown in Fig.3 against the remote side of the expiring stub, thus severingthejexhausted web from its spindle, and that spindle can be raised againby operating the same hand wheel 27. 'Its rotation stops of course.

Whenthe roll B is about to become exhausted a new web roll A is put intothe upper bearings, as indicated in Fig. 4, and then by manipulationssimilar to those above described the exhausted stub B is broughtup intothe full line position in that figure,

and the webs secured together as above described. Then the arm 34 isbrought around in the opposite direction so as to sever the old web, asindicated in Fig. 4.

This is a simplification inseveral respects and an' improvement over theprlor devices which I have designed for this general purpose.
